條件狀語從句和其他從句一樣,學好的關鍵都是掌握好引導詞,然而除了常規(guī)引導詞以外,還存在著一些特殊引導詞,掌握好這些引導不僅能讓你的英語水平更上一層樓,也能讓你的日常交流表達更加地道。

suppose和supposing:

suppose和supposing可用作連詞,引導條件狀語從句,其意為“假若”“如果”等;此時主句通常為疑問句。

eg.Supposing he can’t come, who will do the work? 假使他不能來,這工作誰做?
???? Supposing he does not come, shall we go without him? 如果他不來,是不是不帶他去?
???? Suppose you were given a chance to study in America, would you accept? 假如給你一個到美國學習的機會,你會接受嗎?
???? Suppose [Supposing] (that) we miss the train, what shall we do? 假如我們誤了火車,我們將怎么辦?

provided和providing:

雖然 providing 和 provided 形式上為動詞provide的現(xiàn)在分詞和過去分詞,但它們均可用作連詞,引導條件狀語從句,其意為“只要”(=as long as)、“如果”(=if)等。

eg. Providing [Provided] you clear your desk by this evening, you can have tomorrow off. 只要你到今晚把案頭上的工作做完,你明天就可以休息。
???? Providing [Providing] you promise not to tell anyone else. I’11 explain the secret. 只要你保證不告訴任何人,我就把這個秘密講給你聽。
???? Provided [Providing] that you keep quiet, you can come to the concert. 只要你保持安靜,你就可以去聽音樂會。
???? Providing there is no opposition, we shall hold the meeting here. 如果沒人反對我們將在這里開會。

這類從句通常置于主句之前,但置于主句之后也是可能的。

eg.I will stay here provided [providing] the climate agrees with me. 如果這里的氣候合適的話,我就待下來。
???? You can borrow my bike providing [provided] you bring it back. 你可以借我的自行車,只要你還給我。?

以上就是關于特殊引導詞的知識點了,掌握好這些特殊引導詞,不僅能夠讓你在考試中更有優(yōu)勢,更能讓你在日常交流中更顯地道自然,一起加油學習吧!
